Except you didn't really explain anything. You said wave dash when full screen, something about Emerald Defender which I didn't even ask and check every staff normal with B4, hit her with it and then start oki.
Your "check and hit her with B4" operates under the same idea then. As if she will always get hit and then it's free oki. It will not. She's -13 and she can block. She can also be +3 instead because she can cancel it into running Nitro Kick which will always leave her at perfect D4 distance to abuse it all over again. Only after a D4 ON BLOCK she has so many options while all you have is B4. Hell she can even cancel D4 into projectile and you can't do shit about it even if you duck it. Imagine having to guess so much when it's supposed to be your turn.
So what am I missing here?
Your original question about the Jade match up was vague(in the other thread) if you only wanted to discuss Jaded versus her you should have said so instead of acting like how she does against ED is irrelevant when it isn't. It would be beneficial when you don't agree with someone to ask well which match up cause I think Jaded is this.
IF you're going to look at things in a very linear minded way it's never going to be a productive conversation. The reason why I am mentioning back 4 is she cannot escape after that when she's a certain frame amount negative and it sets up your oki if she doesn't respect you. Garnering respect is all about conditioning people to react a certain way and once you get people to act a certain way you can start throwing them, micro dashing up, baiting a down 2, mid staggers etc. That's how you craft a meta. If I'm making sweep seem like a big deal it's because it is (similarly to how down 4 is a big deal for Jade/imagine that).
Nobody ever said to only do that and never do anything else. It's a bad faith scenario. Characters like Jade rely on spacing you out if you can check her backward movement and set up your own game that is extremely beneficial to utilize. We also have a rewarding crushing blow off overhead if we punish a whiffed poke even that should discourage mindless poking if you're a Sheeva that spaces her out appropriately. The jade sounds like they're abusing down 4 constantly so it can't hurt to concede that aspect and use that strength against her right?
Down 4 into straight glaive sails over your head. Whiffed glaive at that range isn't plus when you duck it so she can't do whatever after it. Also down 4 on hit jails into straight glaive from what I can tell, but it's -14 on block if she wants to do that and if she does ex glaive to make it safe you can duck under it and punish her because the ex hit advances her forward and is a high so 1,2 ex grab or shield pop or whatever variation gets a combo. On whiff straight glaive is -22 but due to wind up is not full combo punishable on its own, but I can check it on block after it whiffs offline depending on what you wanna do you may have to micro dash.
As for ex shadow kick on block obviously it's good, but nobody on the roster has any counterplay for it because it's plus 3 on block and gapless lol. It's nothing unique to Sheeva or the match up. It's not your turn so nobody has a solution for it. There's no solution for Kung Lao's ex hat spin on block, but Jade still beats him for example.
The only super match up specific thing is run getting her out of dodge versus telestomp but stomp shouldn't be the core of your play with Sheeva cause it's not a move intended for that purpose, it's more of a move to force movement and counterzone. Let's also keep in mind if the Jade wants to end in pole vault she's negative in your face. This variation of Jade has to approach you in order to damage you so her out spacing you means a lot less when her entire game revolves around safe chip and block pressure up close. She also relies on people over extending and being sloppy.
People here wanna take super dismissive tones with people (I'm not struggling with Sheeva or with Jade in this match up).
